Troubleshooting

What to try first:

  • Check for any known issues or gotchas on the Compatibility page.
  • Format with SD Memory Card Formatter Chose the “Overwrite format” option.
  • Update to the latest version
  • Power the device via USB.
  • Use only ONE image on the SD card, Use one from the Mega drive under the Usage page.
  • Remove all other SCSI devices on the chain.
  • Try a different SD card (different brand)
  • Review your board jumpers and config.
    • Is termination off? Turn it on. Is it on? turn it off. (Usually on is correct)
    • Is PWR_ON jumper on?

When reporting an issue:

  • Include the full log.txt and if present err.txt
  • Enable debug in bluescsi.ini on the SD Card:
[SCSI]
Debug=1

Specific Issues

The SD card is not recognized (LED Flashes 5x, repeating)

The status LED on the Pico flashes 5 times even though a card is inserted.
* Solution 1
* Use a tool such as SD Memory Card Formatter (see above) to completely zero out the card.
* Solution 2
* Use a different SD card

No images found (LED Flashes 3x, repeating)

The status LED on the Pico flashes 3 times indicating there are no valid images found.
* Solution 1
* Verify you are using the correct naming for images. See the Usage page for proper naming.
* Solution 2
* Check soldering to pins on the SD card socket. JLPCB and other board producers are known to sometimes be a bit lax on their quality control.

The external activity LED does not light up

When the computer accesses the emulated disk drive, the activity LED remains dark
* Solution 1
* Confirm the polarity of the LED
* Solution 2
* The computer may not be providing enough TERM power on the SCSI bus. Measure voltage on the PWR_ON header. If it measures below 4V try supplying external power through the berg connector on the BlueSCSI.

[Mac] LED flashes on the Pico and flashing question mark is on the screen.

This usually indicates you have an image that does not have an operating system on it, or you are using an image meant only for an emulator.
* Solution 1
* Use a pre-made image, pre-made blank, or Disk Jockey to create your image. This will ensure it’s a drive image.

Your SD Card may be too old/slow to keep up with your SCSI bus. Try a newer, higher rated SD card. Format with SD Memory Card Formatter Chose the “Overwrite format” option.
